Core i5-1335U vs Core i5-1135G7

The similarities between the two CPUs include L2 Cache per core capacity, maximum memory capacity, and the PCI Express revision. The two GPUs also have the same iGPU, potentially matching base TDP ratings.

Architectural Differences

  1. Core/Thread Counts: The Core i5-1335U adds specialized E-cores (two of them) to its arsenal, along with 8 P-cores. So overall, the Core i5-1335U has 10 cores compared to 4 of the Core i5-1135G7. As for thread counts, the Core i5-1335U rocks 12 over 8 of the Core i5-1135G7. 
  2. Clock SpeedsThe Core i5-1135G7 has its base frequency configurable between 900MHz and 2.4GHz. Meanwhile, the Core i5-1335U clocks a fixed base speed of 1.3GHz (P-cores) and 900MHz (E-cores). As for boost frequencies, the Core i5-1135G7’s cores can be bumped up to 4.2GHz compared to its Alder Lake rival’s 4.6GHz (P-cores) and 3.4GHz (E-cores).
  3. Memory: Regarding memory support, the Core i5-1335U further improves DDR5 and LPDDR5 support over Alder Lake and also adds LPDDR5x support. On the other hand, the Core i5-1135G7 does not have DDR5 or LPDDR5 support at all. It’s limited to DDR4 and LPDDR4x (the Core i5-1335U also supports these memory types at the same speeds in addition to DDR5).
  4. Cache: Although the Core i5-1135G7 has a higher L1 cache per core capacity (96KB over 80KB), its overall L1 capacity is less, courtesy of its lower core count.
    The same applies to the total L2 cache capacity despite both CPUs having the same cache per core capacity (1280KB). Regarding the L3 Cache, the Core i5-1335U extends its dominance with 12MB compared to 8MB of its Rocket Lake competitor.
  5. TDPLastly, the question of TDP arises. The Core i5-1335U draws between 12-15 watts at base, and the laptop manufacturer adjusts this range. In contrast, the Core i5-1135G7 can draw between 12-28 watts at base. Talking boost TDP, the Core i5-1335U is rated at 55 watts, while the Core i5-1135G7 does not have such a rating.
